This invention aims to provide a means by which the finger nails may be easily, quickly, and thoroughly buffed and polished. 1

rlihe common practice by manicurists is to buff and vpolish the nails by meansY of an elongated b'ungand polishing pad which is reciprocatedhrapidly across the tops'or As these tops or faces are convex, thegreatest amount of polishing is done on the center or tops ofthe nails while a very considerable portion of the Vnail surface about its edges ylies `below thel plane of the adjacent cuticle and cannot thereforey be reached by thejbui'fing pad or satisfactorily polished. .In the effort to polish the edges so far vas it is possibleat present, the manicurist must' bear downV heavily upon the buifing pad and reciprocate itacross the cuticle adjacent to the edges of the nail. This polishes the cuticle as well as the nail and cannoty be avoided by the most skillful use of the buiiing pad, while the heatI developed by the friction of the pad tends to Vburn or a'ccumulatively callous the adjacent 'cuticle, thus necessitating further trimming, removal, or treatment of the same which is undesirable as it promotes further cuticle growth. In addition, when the nails are rfrequently manicured, excessive polishing with the usual means makes the center of the nails vverythin and'causes the formation of unsightly ridges, bulges,

'orv hollows. An additional objection'toY the bufngp'ad when used professionally is thatl the nails of a great many people are `polished with the same pad whichr is unsani? talv- A Y One of the primary purposesof my presentinvention isto provide a means by which nails may'bebufi'ed and polished throughout their 'entire' lareas and around vtheumargins of the nails vas well 'as in the center, thus producing- ,a yuniform ypolish over the entire area ofthe nail. 1 j

Another objectv v1s to :providefa means which will preclude injury or staining by the butfmg or polishing` tool to the cuticle surrounding the nail.

A further object is to provide a machine which will be light in weight so that it can be readilyhandledr by theoperator, one which will provide a plurality of polishing tools or pads, one to be used with bufiing material and the other with polishing mate-V rial,y andL also to provide a machine which can be economically manufactured and will be durable in use and which will comprise replaceable buiiing and Vpolishing pads and replaceable cuticle guards or protectors so that fresh pads andl sterile protectors can be used upon each person, thus making the device thoroughly sanitary.

Other objects'and advantages of my invention will be readily appreciated when the same becomes better understood byv reference tothe following description when considered inconnection with the accenn-r panying drawing.

Referring to the drawing: i v

Fig. l. is a side elevation, partially in section, of a buffi-ng machine embodying myinvention, z Fig; 2 is a fragmentary enlarged 'sectionalview showing one ofthe tools and protectors,

Fig. 3 is a similar view showing a modified form of cuticle protector,

Figa is a view of an optional form of replaceable polishing tip, shown in -contact Vbeing provided with oppositely extending bearings 9 and ll respectively, in which is journaled a shaft 12.

f 'The motor shaft lwhich projects axially into the housing 8 is connected to the shaft l2 for the purpose of driving the same, and

while a bevelled or wormvgear or other connection between these shafts may be .employed to impart to the shaft l2 a continuous rotary movement, I have shown a practical'fmethod whereby satisfactory results are obtained by oscillating rather than rotating the shaft l2, and in Fig. l I have illustrated a preferred connection between these `shafts for effecting this movement. The motor shaft 18 is therefore provided with ank eccentrically disposed driving stud i" u14; which may be 'secured to the shaft in any suitable manner, but is herein illustrated as being seated in a socket formed in a lcollar 15 which is fixed to the shaft 13 by a set screw 16.

formed in a collar 18 secured to the shaft 12 by a set screw 1.9. This whole assemb'lyis inclosed and protected by a vremovable Vcap 21 fitting over the outer end f the 'casing 8.

y j The stud 1 4, as it rotates with the motor ashaftl, reciprocates inthe groove 17y of 'the collar `18 and imparts to this collar and to the shaft 12 towhich thecollar isiixedly secured,a rapid oscillatory movement'. "The tool Vor tools, which will be AAlater'described,

52 carried' by the shaft12, Itherefore'partake of an oscillatory movement whichIhave foundto .be quite satisfactory in accomplishingthe desired, results. I donot con- A line myself to Amotor drive' forjthis purpose, '1? however, as the oscillatory movement 'of the tool or tools can very well be suppliedby a flexible shaft operating.y from a-jdistant v source or4 by means 'of4 anfelectromagnetic Referring; now to Fig. 2, 'it will be observed thatthat portion ,of the shaft-12`pro ecting beyond thevbearing 9 comprises' a reduced portion 22,`and its outer end preferably, although not necessarily,'is provided 1 .with a cushionv 23.in the'form'ofa piece of rubber or other suitable,` material. 'Around the end of' the shaft there isiV disposed a tip indicated generally Vby reference character 24, which consists Lof Va 'piece of; suitable bulfing 4. and"` polishing material" such Mas V chamois skin which is wrapped over I the Vend of the shaft 12 and issecured to the shaft by Awrapping a'cor'd .or string ,25V around'thetip where rit surroundsthe reducedportion 22 of the shaft 12. 4A rubber ployed if preferred.

An optional construction is illustrated in.. 4, wherein a cap 30 of metal, rubber, Vor other suitable material slips tightly over Fig.

ythe end of shaft 12 sothat itA will ypartake ,of any motion of the shaft; 4A small disc or tip ofa suitable buiiingorpolishing material such asy chamois skin, wirk, felt, or

leather 244 is firmlyx attached or'cemeiited to v. the end of Vthe cap 30 thus .providing'a means whereby the Vminimum of such buiiing or polishinglmaterial isemployedand the bufiing orpolishing material for this'means .or purpose however ,or to any means of at- I do not confine myself Eto any particular x taching tool or tip tothe shaft 12 but The projecting end ofthe 'stud 14 projects into aI longitudinal groove 17 Smale, so that um expbsa'ena er up Win buff or polish the nail.

`In order to prevent burning, abrasion, or

injury ofthe 'cutic'le at the edge of the nail by therapidmovement of the side walls of the tip 24, my invention contemplates the provisionV of a protector, guard, or shield 26,"whic`h will""prec`lude Contact of the side .walls of the y tip24` with the cuticleV The vform ofguard'shown in Fig. 2 comprisesa cylindrical member, 26 made 'of' any 'suitable material but preferably of a non-metallic Y nature such as Celluloid or fiber. This protector isradapted to slip overfandrsnugly lit the" perimeter of bearing '9 while 'its other end is reduced jinf diameter to closely ap- Y :preach the. side ywalls of' the V"buffing Torfpol- Mishing tip `24.' While there is normally some space between the tipi 24 'and'. the jprotector 26," it is evident that in operationthis space may become Afilled' with excess fbu'fiing Aor polishing powderor the pressure "of tool on the nail and against the'edge ofthe cuticlefmayn force Ythe tip and theprotector f Either' of Vthese conditions "will result in wearing away theprotectorfmaterial 26 and it is evident that thekmaterial so worn`awa'y1ca`n easily deposit in tliejoint betwee'n the nail and the' cuticle". o Asthis must be washed or cleaned out fitV is apparent that the protector material shouldipreferably'be ofy a non-metallic nature an'd of a 'light color so'that the surrounding fciiticle or tissue will notv be indelibly'stainedor' left in unsightly condition.

The protector `is" i'emovablefor cleaning or other purposes and VAmay Vbe readily slipped off. when. desired and the" tip 24 "panbe rreadily detached from theshaft 12 ,after the removalfof vthel protector;4` Botlrthe tip .and thepifotectoig therefore, are readilyre- :movableand replaceable so `that a fresh vtip z and clean! or sterile protector may' be used [for each person, thereby making the device entirely sanitary.

In this instance,"thefprotectoif-lwill, lof

'i While the machine 1nay'-be'so constructed onlyof the casing 8, and the machine, will have but one'tool'or tip',I prefer that' iti-be il L? lthatwthe shaft 12 w'illQproject onesideV whole can-.be quickly attached or'detached.v

equipped rwith afplurality'oftools which may be of various sizes, but fin practice,

when adapted to be used with differente buffclaim any meansY for achievingthis end when attached to a rotating or oscillating' CII In the form shown in Fig. l, the tip 28, at the opposite end of the shaft and tip 24, is preferably made of a rougher or harsher material than that used on the tip 24, so that it can be employed in removing stains from the nails and also from the lingers, if desired. rIhe tool 28 may also be larger or, if preferred, smaller than the tip 24, and the gua 1d or protector 29 will be of correspendi ng dimensions.

In the use ot a machine embodying my invention, the tip to be employed is dipped in the polishing or buiiing material and While being oscillated by the rapidly revolving motor, is traversed over the nail under such pressure as the manicurist may deem necessary to apply. The tip, being relatively small, is capable ot being moved over the entire surface of the nail and close to the edges thereof, and all danger of injury to the surrounding cuticle is obviated by the cuticle protector surrounding the tip, and which may be moved into intimate Contact With the cuticle Without injury thereto.

While I have shown and described a preferred embodiment ot' the invention, the structural details may obviously be varied Within considerable limits Without departing from the essence ot the invention as delined in the following claims.

I claim:
